Application filed September 22, 1914-.

To all whom it may concern:

Be it known that I, Gnxn'rnny N. SQUInns, a citizen of the United States, residing at Greenport, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in carbureters and has for its principal object to provide a carbureter wherein the supply of gasolene and air is simultaneously controlled upon movement of the throttle lever which controls the feeding of the mixture to the cylinder of an in-v material saving of fuel over the carbureter. of ordinary type by passing the mixture through a wire screen or perforated disk as it leaves the carbureter.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which:

Figure 1 is a view in elevation of the air-intake side of the carbureter.

Fig. 2 is a top plan view of the carbureter.

Fig. 3 is a vertical sectional view-*through the carbureter.

Fig. 1 is a horizontal sectional view, taken on the line 4t of Fig. 1.

Fig. 5 is a detail view of the needle valve and controlling means thereto, and

Fig. 6 is a detail sectional view of the valve controlling the supply of mixture to the cylinders of the motor on which the device is in use.

eferring now to the drawings by char acters of reference, the numeral 1 designates as an entirety the float chamber of the carbureter which comprises the cylinder 2 having formed at the lower left hand corner aperture 4t, the use of which will appear as the description proceeds, A threaded plug Specification of Letters Patent.

Serial No. 862,976.

5 is arranged to be screwed into the upper end of the cylinder 2 and this plug is provided with suitable connections 6 by means of which the device is connected to the fuel supply. A central rod 7 is operatively mounted within the cylinder 2 and has secured thereto the cork or similar float 8 which is arranged to control the flow of the fuel from the fuel supply into the float chamber. X designates a small hollow plug with central rod for pushing down the float to admit extra gasolene into the float chamber. A suitable tubular member 9 is formed at the bottom and to one side of the float chamber and terminates in the up wardly extending tubular member 10. A suitable internally screw threaded aperture 11 is formed in the tubular member 10 near the point where it oins the tubular member 9 and this aperture is arranged to receive the plug 12 which is provided to permit the contents of the float chamber to be drained. The tubular member 10 is provided near its upper terminal with the beveled upper face 1% forming the valve seat with which the needle valve which will be more fully hereinafter described, is arranged to cooperate. Extending upwardly from the valve seat 14% is a suitable cylindrical wall 15 which is provided with the internal screw threads 16 in its upper extremity. Threaded into the wall 15 at a point slightly above the valve seat 14; is the laterally extending stem 17 having a gasolene canal 17 which projects through the wall of the carbureting chamber designated generally by the numeral 18 at a point substantially 30 degrees to the tubular member 9 to provide a stop to limit the movement of the cylinder 23 which will be hereinafter more fully described. The mixing chamber hereinbefore mentioned com prises the cylindrical wall 18 which is provided at diametrically opposite points with the tubular extensions 20 and 21 which form the intake and outlet ports respectively. This wall is formed integral at 22 with the float chamber 1 hereinbefore described, and it will thus be seen that the cork hereinbefore mentioned will be held at all times against accidental movement and thus in sure the proper positioning of the several elements.

Rotatable in the carbureting chamber 18 hereinbefore referred to is the hollow cylinder or air valve cylinder designated generally by the numeral 23, which comprises the cylindrical wall having formed therein the circular aperture 25. Diametrically opposite the circular aperture is the triangular aperture 26, the apex of which is at a point central of the longitudinal extremities of the cylindrical wall. This cylinder 23 is formed with end closures and these end closures are provided with central apertures 27, the lowermost of which is arranged to surround the tubular member 10. The central aperture in the uppermost end closure is arranged to surround the valve stem 28 which is provided with the threaded portion 30, and is also provided intermediate its ends with the angular wall 31 and terminating in the cylindrical extension 32, as is clearly shown in the drawings, Fig. 5. A suitable lever 33 is clamped around the valve stem 28 by means of. set screw 34 and the valve stem is surrounded by a suitable compression coil spring 35 which is arranged to bear against the lever and against the upper end closure 27 to hold the cylinder 23 in place. Extending upwardly from the cylinder are provided the spaced ears 36 which are of suflicient distance apart to permit the lever 33 to pass therebetween. This lever 33 is provided at its free end with a suitable aperture, by means of which it is arranged to be connected to any suitable controlling mechanism.

Permanently soldered in 21 is a wire screen or perforated plate.

It will be apparent from the foregoing that in use the gasolene which is to be atomized passes into the float chamber 1, from whence it passes through the aperture 4 into the tubular member 9 and thence through the tubular member 10 and valve to the angular extension 17 where it passes outwardly through the upturned, transverse bore. This causes a flow of gasolene at the apex of the triangular opening 26 and the air which passes through the mixing chamber from the side 20 then passes over the gasolene spray and mixes thoroughly therewith and thence to the manifold of the motor on which the device is used. Upon operating the lever 33 the cylinder 23 and valve stem 28 will be rotated and it will be evident that the valve will be raised or lowered and simultaneously the flow of air passing through the carbureting chamber is increased or decreased according to the direction of rotation. This simultaneously causes an increased or decreased volume of mixture to pass through the triangular opening and into the engine manifold, thereby eliminating the necessity of a throttle valve of the butterfly type or any other construction and controlling the mixture of gasolene and air simultaneously with the control of speed or power of the motor.

From the foregoing it will be apparent that a particularly simple and effective device is provided which will eifect considerable economy in the operation of motor vehicles and also provide a device which is easily and cheaply manufactured and may be thereby applied to a motor vehicle of any description without materially adding to the cost.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the invention as defined in the appended claims.
